Fistula formation is one of complications after surgery. Additional surgical intervention is recommended when fistula does not respond to conservative therapy. Eight patients with fistula were treated by using a baby feeding tube or double lumen angiographic catheter with fibrin glue. All the fistulas except one were successfully treated; 6 with complete occlusion and one with decreased discharge from fistula. It is emphasized that two deep fistulas could be occluded by using angiographic technique. Our preliminary result suggests fibrin occlusion therapy of fistulas is a safe and useful procedure, and an alternative to surgery for non-curative fistula.
